Can anyone please recommend a good plugin to replace built-in vim regex search with PCRE regex?

• eregex.vim

  2 209 0.0 VimL

  Perl/Ruby style regexp notation for Vim

I think eregex.vim was the plugin I last saw that did this, but I haven't tried it. I don't like putting too much between me and /. I use /\v when I want something closer to PCRE.

• vim-grepper

  19 1,198 3.9 Vim Script

  :space_invader: Helps you win at grep.

This wouldn’t be a direct replacement for searching, but could you create/find a tool which uses perl regex to fill the location window? e.g you can use vim-grepper and modify the rg command with --pcre to use the pcre2 engine.

• RE2

  49 8,607 8.9 C++

  RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python. It is a C++ library.

  

In case it matters, PCRE is not 100% compatible with Perl regular expression syntax, and both have differences from Perl-inspired regexes in various programming languages. This table lists some differences between engines, though it omits Vim's syntax. The RE2 syntax page has details on Perl, PCRE, and Vim syntax as they differ from RE2.

• ripgrep

  348 44,747 9.3 Rust

  ripgrep recursively searches directories for a regex pattern while respecting your gitignore

I’m no expert, but I believe ripgrep will do PCRE, and there are more than a couple vim plugins that’ll leverage it. I happen to use vim-ripgrep, which is good enough for me, but not sure if it’ll let you get at the PCRE option (I’d guess it should, but I haven’t checked).
